Yonah 1:15-17

Orthodox Jewish Bible

¹⁵ So they took up Yonah, and cast him forth into the yam [see Yeshayah 53:5,8; Mt 12:39-40; 16:4]; and the yam ceased from her raging.

¹⁶ Then the men feared Hashem with a yirah gedolah, and offered a sacrifice unto Hashem, and vowed nedarim.

^17 (2:1) Now Hashem had prepared a dag gadol (great fish) to swallow up Yonah. And Yonah was in the belly of the dag shloshah yamim and shloshah leilot (three days and three nights).
